Thought I'd jump in here quickly and respond to a couple of points.
Pat, if you're interested in a Lamello biscuit joiner, I do have standard measurement scale stickers that you could use if you'd like (and you are correct, all Lamello machines come from the factory with metric-only scales).
A general response to Scott and all: The Domino is a fine tool. In fact, I'd probably have one myself if I decided to get back into studio furniture again for leg-to-table joinery. However, I can say that a biscuit slot made with a Lamello machine is a very fast process with much more lateral adjustability. At $649 for the Classic X machine and a little less than $0.05 per biscuit, it is also quite a bit more affordable than the price range you've suggested. There is a world of difference in quality and precision between Lamello and off-brand machines. You'd know it even just by picking one up in your hands.
Then of course the P-System by Lamello is a giant leap forward in connector innovation. I've included a link to our Lamello Lessons YouTube channel below.
If anyone would like to learn more about Lamello, request literature, or receive a P-System demo block, please reach out to me.
